Middleton was at Wimbledon to watch Serena Williams play Elena Vesnina in the women’s semifinals. Before the match, Middleton was introduced to Williams’ mother, Oracene Price, who will watch both Serena and Venus Williams play.

As she does, Middleton recycled a Roksanda Ilincic sunny yellow dress that she first wore on her tour of Australia with husband Prince William in 2014. She paired it with her go-to Rupert Sanderson Malory nude pumps, which retail for £425, or about $553 at the current exchange rate.
